Creating a Volume on the Lightbits Storage Server

AI Tools

To create a volume on the cluster, log in to any of the Lightbits cluster servers and enter the lbcli create volume command.

Sample Command

lbcli create volume --size="200 Gib" --name=1vol --acl="acl3" --compression=true --replica-count=2 --project-name=default

Sample Output

root@rack03-server72:~ lbcli create volume --size="200 Gib" --name=1vol --acl="acl3" --compression=true --replica-count=2 --project-name=default Name UUID State Protection State NSID Size Replicas Compression ACL 1vol c074cf03-83fb-4c15-a601-5444e798f51f Creating Unknown 0 200 GiB 2 true values:"acl3"

Delete the created volume:

lbcli delete volume --name=$VOLUME_NAME --project-name=default

List Volume Details

lbcli get volume --uuid=$VOLUME_UUID --project-name=default -o json

Sample Output

root@rack03-server72:~ lbcli get volume --uuid=c074cf03-83fb-4c15-a601-5444e798f51f --project-name=default -o json { "state": "Available", "protectionState": "FullyProtected", "replicaCount": 2, "nodeList": [ "cfbfdc90-43b3-5ce6-be99-1ab4171785b0", "3b7a262a-ba3f-5447-9c21-e3c8ed699f0f" ], "UUID": "c074cf03-83fb-4c15-a601-5444e798f51f", "nsid": 4, "acl": { "values": [ "acl3" ] }, "compression": "true", "size": "214748364800", "name": "1vol", "rebuildProgress": "None", "statistics": { "logicalUsedStorage": "0", "physicalUsedStorage": "0", "compressionRatio": 1, "totalCompressionRatio": 1, "physicalCapacity": "0", "physicalOwnedCapacity": "0", "physicalOwnedMemory": "0", "physicalMemory": "0", "userWritten": "0" }, "IPAcl": { "values": [ "ALLOW_ANY" ] }, "ETag": "1", "connectedHosts": [ "acl3: 172.16.231.78" ], "sectorSize": 4096, "projectName": "default", "sourceSnapshotUUID": "", "sourceSnapshotName": "", "placementRestrictions": [ ] }

Check the basic status of the Lightbits cluster through the lbcli command line.

lbcli list nvme-devices

This retrieves a list of SSD devices in the cluster. The list can be filtered to list SSDs that exist in a specific server, are managed by a specific node, or are unmanaged.
